Paramagnetic NMR
Structural Uses of Paramagnetic NMR Paramagnetic effects are measured as differences in NMR spectra recorded from the target molecule in the paramagnetic and diamagnetic states. Data measured with a paramagnetic ion must be compared with corresponding data obtained with a chemically similar but diamagnetic metal ion. Diamagnetic Reference

Electronic Spectroscopy of Transition Metal Complexes
xuv.scs.illinois.eduWhat is electronic spectroscopy? Absorption Absorption of radiation leadi ng to electronic transitions within a metal complex. UV = higher energy transitions: between ligand orbitals visible = lower energy transitions: between d-orbitals of transition metals or between metal and ligand orbitals UV 400 nm (wavelength) 200 700 visible Absorption
Applications of Group Theory to Spectroscopy
xuv.scs.illinois.eduAn FTIR interferogram converts wavelength into mirror position (i.e. energy into time). The central peak is at the ZPD position ("Zero Path Difference") where the maximum amount of light passes through the interferometer to the detector. FTIR Interferogram The interferogram is then fast Fourier transformed (FFT) back into the

This can be very efficient and can lead to featureless broad lines. Sometimes it can be beneficial to add a small amount of paramagnetic impurity if the relaxation times are very long.
